Communication number compression encryption method, system and device

Abstract

The invention discloses a communication number compression and encryption method, system and device. The method comprises the following steps: initializing a password book, loading related routines at an encryption end and / or a decryption end, carrying out on-line work at the encryption end and / or the decryption end, and the like. The system comprises a password book initialization module, a routine loading module and an online working module. The device comprises a data acquisition device, a processor and a memory. By adopting the method, the system and the device provided by the invention, data processing in the aspects of encryption, compression, input or writing error correction, unified expression specification and the like can be carried out on information such as the communication number, the security of the communication number in the transmission process is improved, the transmission and storage overhead is reduced, the cost is reduced, and the communication number is more unified and standardized; and technical support for related work is realized.

Description

technical field [0001] The invention relates to the technical field of mobile communication data security, in particular to a method, system and device for compressing and encrypting communication numbers. Background technique [0002] International Mobile Equipment Identity (IMEI) is used to identify each independent mobile phone and other mobile communication devices in the mobile phone network. The serial number has 15 digits in total, and the first 8 digits (TAC code) are the model approval number, representing the type of mobile phone. The last 6 digits (SNR) are the serial number, representing the production sequence number. The last bit (SP) is generally 0, which is a check code. [0003] International Mobile Subscriber Identity (IMSI) is an identification code that is used to distinguish different users in a cellular network and is not repeated in all cellular networks. IMSI is composed of a series of decimal numbers, most of which are 15 digits in length. This ar...

Problems solved by technology

At present, there are still the following problems in the use of "three codes": it belongs to user sensitive information, and it often faces desensitization problems during transmission and storage to avoid leakage of user privacy information; it is frequently used in some communication big data business scenarios, If the original data is transmitted and stored, it will greatly increase the transmission and storage overhead, which will increase the cost; it is easy to make mistakes in the process of analysis and processing, such as truncation, or writing the number 1 as the letter I, and the error rate is high; in practice There are often inconsistent specifications in use, such as whether the check digit of IMEI is defaulted, whether the country code of MSISDN is defaulted, etc. The representation methods are not uniform, causing troubles in the process of data processing and analysis
